Letters Patent No. 83,177 dated October 20, 1868; antedcted October 3, 1868.

IMPROVE!) METHOD. OF WELDING TIRES.

The Schedule referred To all who/m it mwy concern:

Be it known that I, IsAAo LAMPLUGH, of Peoria, in the county of Peoria, and in the State of Illinois, have invented certain new and useful Improvements in Mode of Welding Gast-Steel Tires for Locomotives and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

In the annexed drawings, making a part of this specification, A represents a cast-steel tire for locomotiveengine or other Wheels.

Said tire'is cast in the usual manner, and the ends thereof are then cut out in diamond-shape, as shown at B, to receive a diamond-shaped plug, B', made to t therein. n

The diamond-shape is best, though a round or square shape might be made to answer the same purpose I nearly as well.

The hole is made in the ends, or between them Where said ends meet, and a plug, B, is inserted therein, when The single plug, or plug which reachesv all of the way* through, is mostconvenient in practice.

C represents a portable furnace, to be attached or secured to any forge by means of hinges on one side at g.

furnace C is made nearly conical, and provided This with slot-s h on opposite sides, so as to just fit over and to in these Letters Patent and making part of the same A,.and is provided with suitable holes or apertures x, through which coal or fuel may be inserted, and to aord a window or chance for observing the heating of the metal of the tire.

When the metal is heated as required, this furnace C may be turned on its hinge at g, and raised oi or away from the object, by means of a suitable hook catching in the hole f.

It will readily be seen that this furnace Will confine the heat to that part of the metal in'side of it, and heat the same much faster and requiring much less fuel than by any known device.

This furnace C may be made of metal and lined with fire-brick or otherwise, as may loe-desired, and may be used with advantage at all forges, so as to conne the heat to the object, and to protect the operator from the direct rays of heat and light of the ire.

By placing the tire A beneath the furnace C, at the point to be welded, and bringing the same up to the heat required, and then nsertingthe plug B in the cavity therefor, the said tire A may be forged and Welded with out any difficulty usually attending the'welding of caste steel tires.

I am aware that various-shaped plugs have been welded between the ends of tires.

What I claim, is-

The combination of the tire A, provided with a vshaped notch at each end, within which is inserted a diamondshaped plug, B, which lis welded to and forms a part of the tire, in the manner and for the purposes set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 1st day of February, 1868.
